Definitions

  • Patent Specification EP-A-0074726 discloses a lamp assembly of this type comprising a light source, a light transmitting member carrying a plurality of strips formed of light absorbing material, baffle elements of light absorbing material extending perpendicular to the surface of the light transmitting member towards the light source with each baffle element aligned with a respective one of the parallel strips, lens means arranged to concentrate light from the light source between adjacent strips and a colour filter located between the light source and the baffle elements.
  • the present invention is concerned with an improvement in or modification to a vehicle lamp assembly of this type.
  • a vehicle lamp assembly comprises a light source, a light transmitting member, baffle elements of light absorbing material extending perpendicular to the surface of the light transmitting member towards the light source, lens means located between the baffle elements and the light source and arranged to concentrate light from the light source between adjacent baffle elements, the ends of the baffle elements abutting the light transmitting member being of a colour chosen in accordance with the required appearance of the lamp assembly when the light source is not illuminated and the rest of the baffle elements being black.
  • a colour filter may be disposed between the baffle elements and the light source so as to produce illumination of the required colour when the light source is illuminated.
  • Such a colour filter can conveniently incorporate the lens means.
  • At least one substantially opaque strip is disposed between each adjacent pair of baffle elements, the lens means being arranged to focus light from the light source through the gaps between each strip and its adjacent baffle elements and on to the gaps between adjacent strips when more than one strip is disposed between each pair of baffle elements.
  • At least the surface of each such strip abutting the light transmitting element is of the same colour as the corresponding ends of the baffle elements.
  • the strips may be uniformly coloured. Alternatively the surfaces thereof facing away from the light transmitting member may be black.
  • the lamp shown in Figure 1 comprises a bulb 10, the light from which is collimated by a parabolic reflector 12 so that a parallel beam is incident on a colour filter 14, the colour of which is chosen in accordance with the required colour of the emitted light.
  • a light transmitting member 16 of transparent material which may but need not necessarily be the outer cover of the lamp assembly.
  • a set of uniformly spaced parallel baffles 18 extend between the filter 14 and the light transmitting member 16 and the latter also carries a respective strip 20 between each pair of adjacent baffles 18.
  • the strips 20 are of width substantially equal to the thickness of each of the baffles 18 and the strips 20 and baffles 18 are uniformly spaced so as to leave gaps of equal width between each baffle 18 and each of its adjacent strips 20.
  • the strips 20 and the front ends 22 of each of the baffles 18 are made of a material coloured in accordance with the required appearance of the lamp assembly when the bulb 12 is off while the rest of each of the baffles 18 is black.
  • the colour filter 14 incorporates lens formations 24 on at least one surface, arranged to focus the collimated light from the reflector 12 on to the gaps between the baffles 18 and the strips 20.
  • the strips 20 and the front ends 22 of the baffles 18 may be coloured red while the filter 14 is red, amber or colourless in dependence on the required function.
  • the complete tamp cluster then presents a uniform red appearance when the bulbs are off, while the direction indicators and reversing lamps show amber and white respectively when illuminated.
  • the strips 20 and front ends 22 of the baffles 18 may be of another colour conforming to or toning with the body colour of the vehicle.
  • the strips 20 are replaced by strips 25, the main part of which is of the same colour as the front ends of the baffles 18.
  • the strips 25 are capped by black portions 25 which prevent transmission of light therethrough.
